Most persons may say no but YES is the actual answer
In the ideal sense the dominance of crypto currencies by women is in great progress. Bitcoin is the most popular crypto currency and therefore a currency of such will be dominated either now or in the future.
Women engage in crypto currency transactions also like men do the reason you may feel they don't is because those that don't have not much idea about it.
Yes, they do, you can't basically know the actual percentage but they obviously do, and I say this because my wife does cryptocurrency trading, and I know a lot of other women who do it as well, so the answer to your question is yes, of course. The world is moving forward at a very fast pace, and women that are smart understand what they need to do to keep up.
Their involvement with cryptocurrencies will surely increase over time as the word spreads around more. I recently saw the news that in a country, women are dominating the male traders and are earning a higher percentage of profit compared to men.
